The same bilateral peripheral radiographs — hands/wrists & feet/ankles — read two ways: a conventional report beside a RheumaView™ structured radiographic report.
Why this is a foundational, representative case
One timepoint, one modality, peripheral coverage only, no prior films; the structural signal is early — soft-tissue and periarticular change without established erosion or deformity. It shows how report architecture differs before damage is obvious. See how case complexity scales ↓.

Pattern summary (research view)
- Structural burden of degenerative OA: mild (DIP and first-MTP predominant).
- Structural burden of erosive inflammatory arthropathy: very low (no erosions or deformity).
- Inflammatory signal is carried primarily by soft-tissue swelling and mild periarticular demineralization, rather than by bone damage.
D · Symmetry & distribution analytics
| Region set | Symmetry (0–1) | Dominant side | Distribution note |
|---|---|---|---|
| Hands — erosions | 1.00 | None | No erosions either side |
| Hands — OA (DIP/IP) | ~0.95 | None | Very similar DIP/IP OA burden bilaterally |
| Hands — inflammatory soft tissue | ~0.70 | Right | Right MCP 2–3 swelling more conspicuous |
| Feet — first-MTP OA | ~0.95 | None | Mild, bilateral, symmetric |
| Feet — enthesis | ~1.00 | None | Small plantar spurs bilaterally; no side-dominant erosive change |
Interpretive note (research tier): the symmetry profile favors systemic / low-grade inflammatory involvement of the hands with right-sided emphasis at MCPs, over a purely unilateral mechanical process; feet show symmetric, mechanical-degenerative behavior with negligible inflammatory structural imprint.
E · Age & context alignment snapshot
For a female in the 65+ age range:
Degenerative load
- Mild DIP and first-MTP OA is within expected range for age and activity level.
- Absence of substantial carpal, midfoot, or ankle OA indicates low overall structural degeneration.
Inflammatory load (radiographic)
- Lack of erosions and deformity indicates no radiographic damage phase of inflammatory arthropathy.
- Presence of MCP soft-tissue swelling and mild periarticular demineralization suggests clinical inflammation that is structurally early / minimally expressed on plain films.
Context alignment
- Radiographs are in line with a phenotype of clinically active but structurally non-erosive inflammatory arthritis on a background of mild age-appropriate OA.
F · QA-style analytic summary (non-blocking, research only)
- Dataset completeness: bilateral hands/wrists and feet/ankles with standard projections; no projection gaps identified.
- Consistency checks: hand and foot structural findings internally consistent with the narrative report; no cross-region contradictions detected.
- Agreement profile (conceptual AI–human concordance, 0–1 scale): detection of erosions ~1.0 (complete agreement on absence); osteoarthritis distribution ~0.9 (high agreement); soft-tissue inflammatory markers ~0.7 (moderate agreement; image-texture sensitivity is lower than human clinical correlation).
These metrics are logged conceptually for research and quality-improvement purposes and have no direct diagnostic role.
Experimental research addendum (prototype indices — exploratory only)
Prototype indices — exploratory only; not validated for clinical decision-making. Intended solely for hypothesis generation and longitudinal research; not for individual patient management.
1 · Peripheral Structural Damage Index (0–100)
- Hands/wrists component: 4/100 (driven by mild DIP OA; no erosions).
- Feet/ankles component: 6/100 (mild first-MTP OA and small plantar spurs).
- Combined peripheral index: 5/100 (very low structural damage burden).
2 · Inflammatory Soft-Tissue Load Signal (0–1)
- Hands: 0.35 (low-to-moderate, dominated by right MCP 2–3 swelling).
- Feet: 0.10 (minimal; no dactylitis or erosive enthesopathy).
- Global appendicular signal: 0.30, consistent with clinically evident but structurally early inflammatory activity.
3 · Radiographic Stability Estimate (5-year horizon — structural only)
- Based purely on current radiographs (no prior images incorporated): projected risk of developing definite erosive changes in the small joints of hands/feet is categorized as low, assuming inflammation is controlled.
- This estimate does not include clinical, laboratory, or treatment adherence factors and should be treated as a research-grade scenario, not a prediction.
4 · Phenotype Anchor (imaging-only)
- OA cluster: mild DIP and first-MTP nodal OA (age-aligned).
- Inflammatory cluster: soft-tissue swelling and mild periarticular demineralization localized to MCPs, right greater than left, with no erosive counterpart.
- Imaging phenotype is closest to: “non-erosive inflammatory arthritis with nodal OA background” rather than classic erosive psoriatic or rheumatoid patterns.
5 · Experimental use note
- tracking structural vs inflammatory divergence over serial studies,
- supporting research on treatment response trajectories in patients with clinically active but structurally non-erosive disease, and
- contributing to anonymized QA / registry analytics.
They are not calibrated to individual outcomes and must not be interpreted as prognostic or treatment-guiding metrics in routine care.
All study views are shown as previews; a representative subset is enlargeable here. Full-resolution de-identified radiographs are available by request and in the image-compilation PDF.
Single-date, one modality, multi-region peripheral coverage. Structure and pattern logic carry the read before damage is established.
Multiple timepoints contribute a baseline; the same structural grading compared over time adds a progression axis.
More than one modality compounds the read; structural, activity, and density domains are reconciled in one frame.
